Title: Tester for thermal head
Inventor: KAWAKAMI TOSHIO
IPC: G01R31/28
Filed: 1982-03-08
Abstract: PURPOSE:To enable the detection of defective elements with the processing of electrical signals by comparing a test signal of a signal generator with output signals of the defective elements connected to the output terminal of a thermal head. CONSTITUTION:An output of a signal generator 1 which supplies a test signal is inputted to an input terminal D1 of a thermal head 2 and a comparator 3 which compares to detect a strain of signals. A test signal inputted into an input terminal of the thermal head 2 is tansferred through IC chips as elements to be tsted of the thermal head 2 and outputted from output terminals D01, D02...D0n provided on each of the IC chips. An output terminal D0n selected among these output terminals is electrically connected to the comparator 3 with a conductor 4. The comparator 3 compares output signals of IC chips as elements to be tested with the test signal to detect data errors of the output signals. Thus, the processing of electrical signals enables the detection of defective elements.

Title: Separation type light pickup device
Inventor: KIBUNE HIDEAKI
IPC: G11B11/105
Filed: 1991-02-05
Abstract: PURPOSE:To reduce the height and depth of the device so as to reduce the size of it by arranging galvanomirror driving mechanism at the right and left hands of a movable part. CONSTITUTION:The device is constructed so that a parallel beam from a beam spritter 4 can be deflected down by a galvanomirror 7 toward a deflection prism 15 and that a movable part 71 can be sandwiched between driving mechanism 74 and 74 from its right and left hands. Accordingly, because the mechanism 74 can be prevented from interrupting the light path between a movable optical system 5 and a stationary optical system 1, the mirror 7 can be installed at a lower position and the mirror can be prevented from protruding upward from a bias magnetic field generation device 11. Because the mirror 7 can be located above the prism 15, the mechanism 74 can be also prevented from protruding downward from a spindle motor 10 and a deflection prism 6. Further because the mirror is located approximately beside the spritter 4, the depth is reduced.

Filed: 1988-02-18
Abstract: PURPOSE:To obtain a positive pole plate which is stable at a high utilization rate and in a charge and discharge cycle by forming a higher-order cobalt oxide having a high conductivity on the surface of active material. CONSTITUTION:Active material of nickel hydroxide is filled in porous metal substrate (first process). Or on the surface of active material of nickel hydroxide is formed cobalt hydroxide, which is heated in existence of alkali solution, so the cobalt hydroxide is changed into a higher-order cobalt oxide (second process). For above processes, the second process is performed after the first process. Or otherwise, the first process is performed after the second process. For a heating process in existence of alkali solution, it is important to change cobalt hydroxide to a higher-order cobalt oxide completely, which requires a processing temperature of over 60 deg.C. However, since nickel hydroxide changes nickel oxide at 220 deg.C or over, the heat processing shall necessarily be performed at less than 220 deg.C.
